Symptoms
Assume that you create an instant message (IM) conversation with other users (either click Meet Now or invite more than three users to an IM conversation) in Microsoft Skype for Business 2016. If a user fails to accept the toast (for example, if the user is away from his or her desktop and misses the toast), a Missed Conversation item is written to Conversation History. But the first IM isn't recorded inside that Missed Conversation item.
Resolution
To fix this issue, install the February 7, 2017, update (KB3141501) for Skype for Business 2016.
